Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, and particularly relates to a foldable filter element. Background Art

[0002] In the fields of air purification, water treatment, etc., as a core component, the performance and structure of the filter element directly affect the filtration effect and service efficiency. The traditional filter element design often adopts a fixed shape and size, which is difficult to meet the diverse and complex filtration requirements. At the same time, the storage and transportation of the filter element also face many challenges, especially in occasions with limited space or where the filter element needs to be replaced frequently.

[0003] In recent years, with the development of material science and manufacturing technology, foldable filter elements have gradually emerged. Through ingenious design, such filter elements achieve flexible deformation and compact storage of the filter element, not only improving the filtration efficiency but also reducing the storage and transportation costs. However, there are still many deficiencies in the structural design and connection method of the existing foldable filter elements, such as complex connection structures, easy to be damaged, and difficult to form a stable spatial shape, etc.

[0004] To solve the above problems, the utility model proposes a new foldable filter element design, aiming to improve the flexibility, adaptability and service efficiency of the filter element by optimizing the connection structure and folding method. Content of the Utility Model

[0005] The purpose of the utility model is to provide a foldable filter element to solve the above problems existing in the prior art.

[0006] To solve the above technical problems, the utility model adopts the following scheme:

[0007] A foldable filter element includes filter elements. A plurality of filter elements form a filter element group. The adjacent filter elements forming the filter element group are connected through a flexible connection structure. And each filter element group can enclose different spatial shapes through different shapes of the filter element. The edges where the enclosed spatial shapes cannot be closed are free ends. The flexible connection structure is divided into a long connection segment flexible connection structure and a short connection segment flexible connection structure.

[0008] Further,

[0009] The long connection segment flexible connection structure includes two fixed ends in a "匚" shape at both ends and a middle connection segment in a "一" shape. There are two fixed ends in a "匚" shape at both ends. When the long connection segment flexible connection structure is placed horizontally, the openings of the two fixed ends in a "匚" shape at both ends face away from each other, and the middle connection segment in a "一" shape is vertically connected to the two fixed ends in a "匚" shape at both ends.

[0010] Further,

[0011] The short connection segment flexible connection structure includes "U"-shaped fixed ends at both ends. When the short connection segment flexible connection structure is placed horizontally, the openings of the two "U"-shaped fixed ends at both ends face in opposite directions, and the relative edges of the sides of the two "U"-shaped fixed ends opposite to the openings are movably connected, and both "U"-shaped fixed ends at both ends can rotate around this edge.

[0012] Further,

[0013] The position where the "one"-shaped middle connection segment is vertically connected to the two "U"-shaped fixed ends at both ends should be on the surfaces of the two "U"-shaped fixed ends at both ends where the openings face each other, and at the connection between this surface and the upper surface or the lower surface.

[0014] Further,

[0015] The length of the "one"-shaped middle connection segment is the sum of the thickness of the filter element and the thickness of the upper surface or the lower surface of the "U"-shaped fixed ends at both ends.

[0016] Further,

[0017] The free end can be sealed and connected by means of adhesive tape, snap fastener, buckle lock, magnetic attraction.

[0018] Further,

[0019] The filter element group needs at least 3 filter elements to form, and the connection structure between the filter elements in the filter element group adopts a long connection segment flexible connection structure or a short connection segment flexible connection structure or a long connection segment flexible connection structure and a short connection segment flexible connection structure.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. Through the design of the long connection segment and short connection segment flexible connection structures, the filter element group can enclose different spatial shapes (such as cube, cuboid, etc.), adapting to various filtration requirements and usage scenarios. The flexible connection structure allows the filter elements to form different angles, enhancing the spatial variation ability of the filter element group.

[0022] 2. The filter element group realizes compact storage through alternate folding, which is convenient for storage and transportation. The design of the "one"-shaped middle connection segment of the long connection segment and the movable connection of the short connection segment enables the filter element group to maintain structural stability during folding and unfolding, and the operation is simple and fast.

[0034] Example

[0035] See Figures 1 to 7 :

[0036] A foldable filter element includes a filter element 1. A filter element group is formed by multiple filter elements 1. The adjacent filter elements 1 forming the filter element group are connected by a flexible connection structure 2. Each filter element group can enclose different spatial shapes through the filter element 1 and each filter element group can be folded and stacked. The edges of the enclosed spatial shape that cannot be closed are free ends 3. The flexible connection structure 2 is divided into a long connection segment flexible connection structure 20 and a short connection segment flexible connection structure 21.

[0037] Each filter element 1 is connected by a long connection segment flexible connection structure 20 or a short connection segment flexible connection structure 21 to form a foldable filter element group. No matter what state the filter element group is in, the filter elements 1 therein are all an integral whole, and the integrity of the filter element group can be ensured without disassembling the flexible connection structure 2. The folding and storage of the filter element group is completed by the alternating folding of each filter element 1.

[0038] Furthermore,

[0039] The long connection segment flexible connection structure 20 includes a "C"-shaped two-end fixed end 4 and a "-" shaped middle connection segment 201. There are two "C"-shaped two-end fixed ends 4. When the long connection segment flexible connection structure 20 is placed horizontally, the openings of the two "C"-shaped two-end fixed ends 4 face away from each other and are adapted to the filter element 1. The "-" shaped middle connection segment 201 is vertically connected to the two "C"-shaped two-end fixed ends 4.

[0040] The long connection segment flexible connection structure 20 is provided. The filter element 1 is placed into the opening of the "C"-shaped two-end fixed end 4 by using the "C"-shaped two-end fixed end 4 and fixedly connected to the filter element 1. A freely foldable "-" shaped middle connection segment 201 is arranged between the two "C"-shaped two-end fixed ends 4, ensuring that the two filter elements 1 connected by the long connection flexible connection structure 2 can form different angles, and at the same time allowing a larger change range in the spatial shape of the filter element group to adapt to different filtration requirements.

[0041] Furthermore,

[0042] The short connection segment flexible connection structure 21 includes a "C"-shaped two-end fixed end 4. When the short connection segment flexible connection structure 21 is placed horizontally, the openings of the two "C"-shaped two-end fixed ends 4 face in opposite directions, and the relative edges of the sides of the two "C"-shaped two-end fixed ends 4 opposite to the openings are movably connected, and both "C"-shaped two-end fixed ends 4 can rotate around this edge.

[0043] The two ends of the "C" - shaped fixed ends 4 are movably connected, which increases the flexibility of the filter element group, enabling it to be folded and unfolded more easily while maintaining the compactness of the structure, facilitating use and storage.

[0044] Furthermore,

[0045] The position where the middle connecting section 201 of the "one" - shaped is vertically connected to the two ends of the "C" - shaped fixed ends 4 should be on the surface where the openings of the two ends of the "C" - shaped fixed ends 4 face each other, and at the connection between this surface and the upper surface or the lower surface.

[0046] Furthermore,

[0047] The length of the middle connecting section 201 of the "one" - shaped is the sum of the thickness of the filter element 1 and the thickness of the upper surface or the lower surface of the "C" - shaped fixed ends 4.

[0048] This ensures the tightness and stability of the connection structure, enabling the filter element group to maintain a consistent shape and structure when folded and unfolded, improving the reliability of use, and enabling the middle connecting section 201 of the "one" - shaped to seal the connection between the two filter elements 1.

[0049] Furthermore,

[0050] The free end 3 can be sealed and connected by means of adhesive tape, snap fasteners, buckles, or magnetic attraction.

[0051] Seal the formed space filter element 1 to ensure that the inside of the filter element 1 is a sealed space, enhancing the purification effect of the space filter element 1.

[0052] Furthermore,

[0053] The filter element group requires at least 3 filter elements 1, and the connection structure between the filter elements 1 in the filter element group adopts a short - connection - section flexible connection structure 21 or a long - connection - section flexible connection structure 20 and a short - connection - section flexible connection structure 21.

[0054] According to actual needs, arrange the filter elements 1 to form the appearance when the filter element group is unfolded and connect the filter elements 1 in the filter element group by means of the flexible connection structure 2, finally obtaining the filter element 1 with the desired spatial shape, providing greater flexibility and adaptability, enabling the filter element group to be flexibly configured according to different filtration requirements and usage scenarios, and improving the overall practicality and efficiency;

[0055] Embodiment 2:

[0056] The spatial shape formed by the three filters 1 is a triangular prism. In this embodiment, only the short connection segment flexible connection structure 21 is adopted for the connection mode of the filters 1. By enclosing them in sequence, the simplest spatial filter 1 is formed. When storage is required, each filter 1 is overlapped in different folding directions in sequence, so as to realize the storage and stacking of the filters 1, which is convenient for transportation.

[0057] Embodiment 3:

[0058] Among the filters 1 forming a spatial structure, it is relatively special to enclose a cube or a cuboid. The enclosed spatial structure can be divided into 4 faces or 5 faces by the surfaces, and the long connection segment flexible connection structure 20 and the short connection segment flexible connection structure 21 are adopted. When the enclosed filter core has 4 faces, since the "one"-shaped middle connection segment 201 is equal to the sum of the thickness of the filter 1 and the thickness of the upper surface or the lower surface of the "匚"-shaped two ends fixed ends 4, in order to realize the function of folding and storage, its unfolded structure must be four filters 1 arranged side by side, as shown in the figure. As described above, when it has 5 faces, its unfolded structure must be "L", as shown in the figure. Only in this way can the filters 1 in the filter element group be overlapped and folded for convenient storage.

[0059] Embodiment 4:

[0060] Evolved from the structure of Embodiment 2, the connection mode between the filters 1 is all changed to the short connection segment flexible connection structure 21, and one of the filters 1 in a pair of opposite filters 1 is replaced with two short filters 5 connected by the short connection segment flexible connection structure 21, as shown in the figure. The structure in this embodiment needs to meet that the number of the short filters 5 is an even number greater than 2 to ensure that the filters 1 are folded uniformly and can be folded and unfolded conveniently and quickly. If the number of the short filters 5 is an odd number, it will cause difficulties in the arrangement of the fan in the air purifier. The figure in the folding process of this embodiment is as shown in the figure.

[0061] The principle of the present utility model is:

[0062] The utility model relates to a foldable filter element. A filter element group is composed of multiple filter elements. The filter elements 1 are connected through a flexible connection structure 2. The flexible connection structure 2 includes a long connection section and a short connection section flexible connection structure 21 for connection, enabling the filter element group to enclose different spatial shapes and achieve folding and stacking. The long connection section flexible connection structure 20 consists of a "C"-shaped two-end fixed end 4 and a "-"-shaped middle connection section 201, allowing the filter element 1 to form different angles to adapt to different filtration requirements. The short connection section flexible connection structure 21 is movably connected through the "C"-shaped two-end fixed end 4, increasing the flexibility of the filter element group and facilitating folding and unfolding. The free end 3 can be sealed by means such as adhesive tape and snap fasteners to ensure the sealing performance of the filter element group. The filter element group is composed of at least 3 filter elements 1, which can be flexibly configured according to actual needs to form different spatial shapes (such as a cube, a cuboid, etc.), and achieve compact storage through alternating folding. Through the flexible connection structure 2 and the folding design, the utility model improves the flexibility, adaptability and use efficiency of the filter element group, is applicable to various filtration scenarios, and is convenient for storage and transportation.

[0063] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiments within the spirit and principle of the present invention still fall within the protection scope of the technical solution of the present invention.
